TO ALL WHOM IT MAY CONCERN:

Be it known that I, M. AAVERY, of Groton, in the county of Tompkins, and` State of New York, have invented a new and improved Butti-linge; and I do hereby declare that the followingis afull, clear, and exact I description thereof, which will enable those skilled in the art to make and use the same, reference beinghad to the accompanying drawingsQforming part of this speoiication, in nhicli- Figurel represents a front view of a. door hung on my hinges.

Figure 2 is a transverse section of the same, the line a' z, iig. l, indicating the plane of section.V

Figure 3 is a longitudinal central section of the hinge detached. I

Similar letters of reference indicate corresponding parts.

The object of this invention is to construct a reversible oose-jointed butt-hinge; one that will hang adoor to swing to the right or to the left, and allow of lifting ofi' the same, as ordinary butt-hinges, and which is smooth and even all round, in whatever position the door may be brought. v

My hinge is composed of twohalvrcs, and B. The half A, which fastcns to the jamlo, is provided with l holes, which are countcrsunk both Ways, so that it can he fastened to either side, for right or left, and the socket a, 'which supports the pivot b, is secured in the middle of' the bracket A, projecting equally on either side. .The other half, B, which fastens to the door, is provided with nn eye, c, intended. to catch over and turn on the pivot b of the halt' A. This eye is-situatcd exactly in the middle ofthe length or hei'ht of the bracket B, so that said bracket can be secured to the door, either side up, without throwing it outof position. When theeye c is dropped on the pivot b, an open space is left between the to'p of the eye and an abutment, d, projecting from the top edge of the half A. This space is just high-enogh to allow of lifting oil' the door.

:yBy the use of my hinge, all the trouble is avoided which arises from the use of the ordinary rghtandlcl`t hand hinge, which, in many cases, compels the workman to run to the store and exchange. his hinges, in order to get the door hung theway it is wanted. By my.hinlge the workman is enabled to hang the door as he may he desired to do, either right or left, and a hinge is obtained which is not liable to get outof order, which is cheap, and very convenient in its operation.

What I claim as non', and desire to secure by Letters Patent,l isn-f ',lhe 1iglit-andlei `t butt-hinge, having the screw -holes countersunk upon each side, when its leaf A is provided with an opening between the socket a and abutment d, for the application of the eye c, of the leaf B, as herein shown and described.
